To all whom t may concern:

Be it known that I, THOMAS BRADY, citizen of the United States, andresident of Bayonne, in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in ConveyerApparatus., of which the following is a specil'ication.

This invention relates to a conveyer apparatus which is speciallyadapted vto charging an ice house with cakes of ice and discharging ittherefrom. The conveyer apparatus may also be used for various othermaterials.

The organization of the invention comprises conveyer with endless linkedchains, which for a portion of their total lengths have journaledtherein rollers, while the remaining lengths of the linked chains aredevoid of rollers. This provides a clearance space for cakes of icehandled by t-he apparatus, to pass between the chains and deposited onthe floor of the building or upon the top face of the tier of icepreviously deposited into the building.

The endless linked chains with their rollers are provided with suitableframing, a drive cage and a take up cage.` Mea-ns are provided forhoisting the frame with its appurtenances, and other means move theframe and its appurtenances to different parts of the ice house in whichit is being used. rThe ice house is provided on the out` side with theusual elevator and conveyer. Suitable gravity conveyers are used tohandle the ice between the conveyer outside of the building and theconveyer with the rollers in the building which' latter is described indetail hereinafter.

In the accompanying drawings and specification some eXemplifications ofthe invention are shown and'described and which may be varied to suitdiiferent situations within the spirit of the claims.

In the channel irons 292 are openings for the stop boardChains 201 and 231 With the appurtenances as already described areprovided for this modilication of the invention. The elevator 235 isshown adjacent to lthe opening 22 of the building. The gravity conveyer240 leads to the table 243. The gravity conveyer 246 connects the table243 `With the rollers 174 of the conveyer A, when said rollers are attheir upper level. The rollers 174 may be modified by `having connectedthereto or formed on i asso/is their cylindrical surfaces the xl-shapedrings 1743. which prevent the ice carried by the rollers from laterallysliding therefrom.

To operate the conveyor apparatus shown in Figs. 1 to 2l inclusive theice is brought up to the opening- 22 ci the ice house, by means of theconvey-er 236 on the elevator 235 in the usual manner. The said elevatorbeing located at dierent levels as the level of the top. tier of the ice245 varies. rllie operator causes the ice to slide down the gravityconveyer 240 to be deposited upon the table 243.' From the latter theice is moved down the gravity conveyer 246 to th.Q rollers 174 of theconveyor A. rlhe said rollers are located in their lower level when thecakes of ice are deposited thereon. The conveyor with the linked chainsF and is now started, by means of the shitting lever 88 and travels inthe direction of the arrow M carrying cakes of ice up to the stop board99. When the iirst cake of ice deposited on the rollers 174 meets thesaid stop board the lower level of the conveyer is fully charged. Theconveyer is kept running in the saine direction and as it travels theportion of the linked chains F and G which is rdevoid of the rollers 174will move to the bottom level of the conveyor A, and the cakes oi icewill drop between said linked chains to the :door of the ice house orupon the top face of the ice already installed. While the linked chainsF and Gr which are devoid oit' the rollers 174 are in their lower level,cakes of ice are not moved down on the gravity conveyer 246. After thecakes of ice have been discharged through the linked chains the operatorraises the conveyer A, by means of the hand chains 216. The said handchains turn the sprocket chain wheels 214 and thereby the shaft 195 isturned1 thus causing all the ropes or chains 201 to simultaneously pullup the conveyei' il.. Next the operator by means oi" the hand chains 215turns the sprocket chain wheels 213 and thereby the trolleys 191 and 221are moved on the 1 beams 190 to another position. rlhe conveyer is thenagain lowered by means of hand chains 216 and the table 243 and gravityconveyors are located in proper position between the conveyors A and 235to again charge the said conveyer A. These operations are continued forthe whole width of the building. Next the conveyer A is located upon thefinished top tier o'l` ice and another tier is installed, the conveyer Abeing gradually moved to the side of the house from which it was moved.

To discharge the cakes of ice from the ice house the rollers 174 may becharged with the cakes of ice to be taken out either when@ said rollersare at their upper or lower levels. operators to deposit the cakes ofice upon the rollers 174. In case the ice is deposited The skids 44 maybe used by the upon the rollers 174 when they are in their lower level,the conveyer is moved in a direction opposite to the arrow M and thestop board 49 prevents the cakes ci ice being deposited in the drivecage D. The cakes of ice are nent directed from the rollers 174 to thegravity conveyor 246. The ice isthen deposited on the table 243 and fromthe latter it is slid down the gravity conveyer 240 and then is led onto the cenveyer 236 ci? the elevator 235, which with this operation islocated below the table 243. ln case the cakes of ice are to be takenfrom the building 2O upon the rollers 174 when they are in 'their upperlevel, the rollers are moved in a direction opposite to the arrow M andthe stop board 52b prevents the cakes of ice being deposited intothedrive cage D. WV hen the cakes of ice reach the stop board 52b they areled out of the house as already described. ln case the cakes' of ice areto be deposited into the building when the rollers are in their upperlevel they are led thereon as alreadyA described and the stop board 99bis used to prevent the cakes being deposited into the take up cage E.

After the rollers 174 have carried the ice 245 so that the first cake isin contact with the stop board 99h, the stop board 182 is inserted inthe frame C and the stop board 52b is inserted in the openings in thechannel irons 45. The conveyer is moved in the direction of the arrow Mwhich will cause the rollers that are in the upper level totake anopposite direction and as the linked chains F and Gr reach the` upperlevel the cakes of ice will drop through them at both the upper andlower levels, between the stop boards 182 and 99h. The same result canbe obtained without using the stop board 182. The linked chains devoidot rollers being about one-half the total lengthy of the endlessconveyer one-half of the same can be discharged as just described. y Todischarge the portion between the stop board 182 and 'the drive cage D,the movement of the conveyor is reversed so that the conveyer at itsupper level will move in the direction of the arrow M, and aboutone-half of the linked chains devoid of links will move to the top leveland one-half will remain on the lower level and the cakes of ice willdrop to the floor of the ice house.

To operate the modification of the invention shown in Figs. 22 and 23the linked chains F and G- are moved in the direction of the arrow N,when the ice is being installed into the building. The stop boards 182and 260'LL are removed and the stop board 321 prevents the cakes of icebeing deposited into the take up cage J. Gravity conveyers are employedto lead the ice from the rollers 174. When the ice is to be taken out ofthe building the operations may be the same as those described for theoonveyer shown in Figs. l and 2., or a conveyer may be ein ployed withthe rollers connected thereto throughout the 1whole oi its length andthe cakes may move through the take up cage H and leave the conveyer atits lextreme right hand end. Willen so used the stop boards 182 and 260are removed. The other operations with this modilication are sirnilar tothose already described.
